Generally, it’s best to go by capability, not by policy.
Any company has to do what the government of its country says. This goes both for the VPN company, AND any exit node country. So you have to always assume that whatever country your exit node is in has full access to the data exiting the VPN there.
Then there’s the technology being used, the expertise with which it is configured, and finally the policies in place for handling and storing your PII.
Mullvad has a strong record on all accounts, even as far as just giving a year’s notice that it will stop supporting OpenVPN.
AirVPN has virtually no track record, fewer details on hardware, configuration, expertise and PII handling, and it’s in the EU, so has to comply with EU laws as well as Italian laws.
Being in the EU means it has to comply with the GDPR, which does have its benefits. But it also means an EU member state could put a gag order on your account and be monitoring all your data without you ever knowing.
So it all comes down to who you want your data to be private from and why.
Personally, I avoid all public VPN services as much as possible, and assume that the only thing they’re really doing is tricking the next service in the hop as to what country I’m connecting from.
